 ### Store Resume
 
+<!-- restating this as a heuristic rather than a high-level description of functionality allows the spec to be useful for new implementers -->
+
 This feature allow a node to fill the gap in messages for the period it was last offline.
 At startup, a node use the Store protocol to query a random node for
 the time interval since it was last online.
-Messages returned my the query are then added to the node local archive storage.
-It is RECOMMENDED” to limit the time interval to a maximum of 6 hours.

 ### Waku Sync

+For the new version. "think of a specification as a heuristic/set of directives that almost form a kind of pseudocode. This becomes easier if you use the RFC keywords for each directive"

 Nodes that stay online can still miss messages.
